@corbidorbi said in Need help making GB screen smaller:
Of course that's buried in a bazillion other lines in the .CFG.
That's because you enabled 'Config Save on Exit' and all the configurations have been dumped in this file. You shouldn't do that, core options are saved by default (in a separate file) and for other options you use 'Save Core Override'.
Replace the retroarch.cfg file contents you have now in the gb folder with
input_remapping_directory = "/opt/retropie/configs/gb/" #include "/opt/retropie/configs/all/retroarch.cfg"After that, start a game and use the RGUI to change the Video Settings, but use the Save Core Override option this time. Re-start the game and see if the changes persist.
Hint: you don't need to download the file from the RetroPie system, just use Samba Share from your Finder to open the \\retropie\configs\gb folder and edit the file directly.
